.AXLE AND BEARING.

SPECIFICATION forming' part of Letters Patent No. 634,774, dated October10, 1899.

Application filed April `29,1li99. 4

To all whom, it may concern/: A 1

Be it known that I, vEUGENE E. STUvEn, a citizen of the United States ofAmerica, residing at Blue Mound, inthe county of Macon and State ofIllinois, have invented certain new and useful Improvements in Axles.and Bearings, of which the following is a speciiication.

My invention ,relates to an improvement in axles and bearings, and theObjectis to provide a simple, inexpensive, and eective construction forthe purposes sought; and it consists in the main of a straight round.wooden axle formed or turned in three successivelydiminishing diameterstoward the extreme alsovformed both inside and outside in threediminishing diameters and adapted to receive andfit the end of theaxle,roller-bearings itted to and encircling the bearing of the skein,a'wheel-hub inclosing and adapted to turn von the bearings, aremovable'nut, and

both its inner and outer ends.

My invention still further consists in certain novel features ofconstruction and co mf binations of parts, which will'be hereinaftermore fully described,and particularly pointed ont in the claim. A

In the accompanying drawings, Eigure l isY a longitudinal sectional Viewof the axle and skein, showing the means for fastening the two togetherat the inner and outer ends and the rollers in position. In' this iigurethe hub is also shown insection, as well as the nut. Fig. 2 is a viewshowing the hub partly removed, which is the positionof parts when' oil#ing and Fig. 3 is a detached view of the nut.

Arepresents a wooden axle formed or turned on threekdiminishingdiameters marked l, 2, and 3, respectively, with theshoulders 4 and 5 between the portions l and 2 and 2 and 3,respectively. These portions are round or cylindrical, or, in otherwords, are perfectly straight and without taper.

B is the skein. This skein coforms in its ting the three diminishingdiameters of the wooden axle securelyand abutting snugly against ytheshoulders 4 and 5. Although the serial No. 715,043. 'mamans place `byfriction, yet, nevertheless, as an additional means for securing it inplace one or more bolts 6 6 are passed through the inner end of theskein, Where they are held by nuts 7 7 in the usual manner, after whichtheir ends are upset, or, it is needless to say, although perfectlyobvious,that rivets or screws could be substituted for these bolts. Anail or screw 8 is driven or screwed longitudinally.

into the extreme outer end of the skein and axle, and thusfbymeans `ofthe screws, bolts,

rivets, nails, or what not at the two extreme' ends of the skein thelatter is securely held on the axle against the possibility of lateralor longitudinal movement, or, in fact, any move ment whatever of theskein with respect 'to the axle on which it is secured. It might also besaid that the tendency of all of these portion of the skein constitutesthe bearing upon which the hub turns, and entirely encircling-thisbearing portion and interposed between it and the bore ofthe hub are theroller-bearings 9 9, which extend. the entirelength of this bearingportion, abutting at their inner ends at `the inner shoulder 10 of theskein and extending at the other ends flush with the outer shoulder 11of the skein. The nut 12 screws onto the outer end of the skein and itsflange 13 is .of sufficient diameter to incluse the ends of theroller-bearing, the nut having that additional vfunction besides theordinary ones of a hub-nut.

To oil or grease the hub, it is merely necessary to remove it part way,as indicated in Fig. 2, the hub in that Way retaining theroller-bearings against displacement, as its bore isr perfectlycylindrical, and it therefore iits these bearings when entirely on orpartly ICO position temporarily or otherwise. In this way the entireinterior of the hub bears equally and uniformly upon the rollers, andthe rollersin turn bear equally and uniformly throughout their entirelengths upon the intermediate hearing,` portion of the skein.

The Construction is a thoroughly practical one, as it can readily beseen that the parts are so constructed as to be possessed of snperiorstrength. At the same time the several parts are simple, and hubsconstructed in this way not only have a minimum of frietion, but alsothey remain lubrieated for a long period and do not Wear out easily orbeeomeinoperative with Wear.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts described Without departing from thespirit and scope of my invention, and hence I do not Wish to limitmyself to the exact construction herein set forth; but,

Having thus described my invention, what I claim as new, and desire toseeuro by Letters Patent, isd y The Combination with a wooden axlehaving the end formed with a series of diminishing diameters and a skeinof corresponding form fitted thereon and Secured at both ends to theaxle, the intermediate portion of the skein being` cylindrical in form,of rollerbearings surro unding the cylindrical portion, a hub having acylindrical bore which surrounds and turns upon the rollers, saidrollers and hub abutting,` the enlarged end of the skein and a nutscrewed onto the portion of the skein having a smaller diameter, withits flange abutting the outer ends of the cylindrieal portion of theskein and reaching over the outer end of the rollers.
